Winged Spike Demon

[o-bugger.livejournal.com]

I'm looking for an AU fic where, whatever type of creature or demon Spike is, he definitely has fangs and wings. I don't want to give more details because I think I'm mixing up a few different fics. It is Spike/Buffy and the kind of creature Spike is has wings are what I'm sure of.  I can't remember if he becomes a special creature with wings or if that's just the norm for the AU story, but it's not Paradox by JackofSpikes. Does anyone have any ideas?
